QINGDAO -- New business models are emerging and the cultural performance market is heating up in Qingdao, boosting the recovery and expansion of consumption in Qingdao.

Qingdao is opening local polar ocean parks free for traffic police officers, bus drivers, firefighters and sanitation workers to honor their hard work keeping the cities clean and orderly.
